A shipping address is an address where a package can be sent.
Shipping addresses are typically used for physical goods, such as books and CDs, but they can be used for digital goods as well.
Shipping addresses are usually provided by the customer in the checkout process when they are purchasing a product online.
Why Do Customers Provide Shipping Addresses?
People tend to think that they don't need a shipping address when they're buying online because it's all virtual. But if they want to get their package delivered, they do need one! If your business sells physical products, then you're going to need a way to figure out where to send those products.
In addition, many people want their orders shipped to another address other than their billing address (especially if someone else is paying for the order). This means that you'll need some way of gathering shipping addresses from your customers even if you're selling only digital goods or services.
